Sure it does. Something that is more efficient and has less inertia would spool faster then a VF39 especially TS.
BTW avcs couldn't ever cause a valve to drop. Ya if it advances or retards too much it could get bend but never drop.
AVCS rarely malfunctions during operation after time but usually on first startup on a motor where the cam gears were sitting without being cleaned or debris gets in them(something else is gonna happen first if that does).
